Specification of Letters Patent. Patented Oct. 14, 1919.

Application filed January 7, 1918. Serial No. 210,620.

To all whom it may concern:

Be it-known that I, RAoUL C. GAUTIER, a citizen ofthe French Republic, and a resident of the borough of Manhattan, in the city of New York, county and State ofNew York, have invented certain new and useful Improvements in Reinforced Concrete Construction, of which'the following isa specification.

The invention is directed to a steel reinforced concrete construction designed to provide a level flatsupporti'ng floor surface on the upper portion thereof anda smooth ceiling construction on the lower portion thereof, which ceiling is unobstructed by supporting beams projecting downwardly below the general lower surface of the reinforced concrete construction.

Such a steel reinforced concrete construction will be referred to herein as a flat-floor.- ing construction, it being understoodithat by this expression is meant a' construction which provides not only-a flat floor'but also the smooth ceiling on the lower portion thereof. x

The flat flooring construction which is the subject of the present invention is sup? ported on posts and that sect-ion which is'sup ported by adjacent posts is herein referred to as a panel. I The several panels are made continuous and thus a fiat'fiooring construction can be of any desired extent, breadth and length provided it has the requisite number of posts or supporting columns. fiThe supporting posts or columns are of reinforced concrete andare provided with heads or caps. Y 1

An object of the present invention isto arrange the steel reinforcing. members-- which are in the form of steel reinforcing barsemployed in the flooring construction insuch a manner as to impart reinforcing qualities to the flat flooring construction in the place where most. needed,- thus properly reinforcing. all parts of said flooring construction. r

Another object of the invention is to locate the steel reinforcing. members or bars of the flooring construction in such a manner that the designer will lmow that allparts are properly reinforced."

A further object of the invention. is to employ andarrange the steel-reinforcing bars in such a manner that they can be readily placed and so that the work of lay ing the concrete and the steel of the flooring can be readily performed. Y

The invention has in view the objects above enumerated as well as other features of advantage hereinafter specified more in detail and set forth in the claims.

As illustrating certain specific embodiments'of the invention reference is madeto the drawings forming a part of this specification and in which drawings,

Figure 1 is a plan View illustrating the reinforcement of an inner panel supported by four adjacent posts or columns and in this figure there is also illustrated the manner in which upper reinforcing members or-bars of'said panelextend into four surrounding adjacent panels. In this figure all reinforcing members or bars located in the upper portionof the Hat flooring construction are indicated by. heavy lines and all reinforcing members or bars in the lower portion are indicated by light lines.

' Fig. 2 is a, plan view illustrating four adjacent supporting posts or columns and the arrangement of the reinforcing members or bars that are in the lower portion of the flat flooring construction. I j

Fig. 3 is a vertical sectional view of the flat flooring construction, takenon the line 33 of Fig. 2,"this figure illustrating a section of aninner panel midwaybetween the posts, andshowing only the reinforcing members employed in the lower portion of the panel.

Fig. 4C is a plan view illustrating four adjacent supporting posts or. columns and the-arrangement. of :the reinforcing members or barsin the upper portion of the flat flooring'construction. i

Fig. 5 is a vertical sectional view of the flat flooring construction taken on the line 55 of Fig. 4, showing only the reinforcing members or bars'employed inthe upper portion of the panel.

The panels shown in Figs. 1 to 5 inclusive are referred to as'inner panels since they are the panels which are not located next to a wall of a building. The panels located next to a wall, orwalls,of a building are referred to as the outer panels.

Fig. 6 is a plan view illustrating the reing forcement of the fiat flooring construction which oins either a side wall or' an end wall of a building. In thisfigure, the same as in. Fig. 1, the reinforcing, members or bars in the upper portion of the flat flooring construction are indicated by heavy lines and all reinforcing members or bars in the lower portion are indicated by light lines.

Fig. 7 is a view taken on the line 77 of Fig. 6 indicating only the reinforcing members or bars which extend parallel and at right angles to the line along which the section is taken.

Referring now to the drawings in detail and particularly to Figs. 1 to 5, A indicates four adjacent inner posts or columns. These four adjacent posts or columns support an inner panel, as it may be called, as well as portions of adjacent panels. The corners of the inner panel are designated by the letters a b 0 (Z and are located over each post. The posts or columns A each have a head or cap A which is built monolithic with the steel reinforced flat flooring construction B.

In making the flat flooring construction suitable forms are constructed into which the concrete is deposited to define the posts or columns A and also to define the flat under surface B that provides the ceiling. Before or during the depositing of the concrete in the forms the several sets of reinforcing members are placed according to the arrangement hereinshown and described in detail. To facilitate a clear understanding of my invention I hereinafter refer to the parts between a and b and also between 0 and cl as the ends ED of thepanel and the parts between 6 and 0 and a and d as the sides SD of the panel. 5

From an inspection of Fig. 2' it will be observed that there are'four sets of lower peripheral reinforcing members or bars designated D, each set comprising rods 1, 2, 3, 4c, 5, 6 and 7. These lower peripherals which are in the lower peripheral portion of the flooring extend from the head or cap of one post or column to the head or cap of an adjacent post or column, the ends of the peripherals extending over the heads or caps A of the columns, but not extending from center to center of the colunnis. It will be noted that the lower peripherals D at the ends ED of the panels extend at right angles to the lower peripherals at the sides SD ofthe panels. i

In the lower portion of the fiat flooring construction there are provided lower intermediate reinforcing members or bars, or lower intermediates. There are two sets of these lower intermediates each set being designated E and comprising rods 8, 9, 10, 11 and 12. Said sets of these lower intermediates cross each other in the center of the panel and the ends extend over or overlap the central portion of the lower peripherals D and in effect become supported over the latter which serve as tension members.

In the lower portionof'the fiat flooring construction there are also provided lower diagonal reinforcing members. or bars, ar-

ranged in two sets, each designated F.

these diagonals carrying the same proportion of the load as the intermediates.

From the description thus far given it will be noted that the reinforcing members or bars are collectively arranged in the lower portion of the concrete where the tensional strains exist and that therefore substantially all of the lower portion of a panel subject to tensional strains is reinforced by tension rods which in this system are placed-in the best location to take care of the stresses found by numerous experiments.

Each panel has upper tension members or bars arranged in sets, which members may be properly referred to as the upper periphery reinforcing members or bars G, (or upper peripherals), the upper intermediate reinforcing members or bars H (or upper intermediates) and the upper diagonal reinforcing members or bars K (or upper diagonals). Each'set G comprises tension rods 18, 19, 20, 21, 22 and 23 which extend parallel with the lower peripherals with which the upper peripherals are in effect associated. The ends of the upper peripherals overlap with their corresponding lower peripherals and provide the reinforcing tension members to take care of peripheral tensional strains created in the flat flooring construction immediately overthe posts, due to a downward deflection or loading on the peripheral portion of the flooring which is. between the posts. The upper and lower peripherals which are arranged along; any one set of posts or columns provide the reinforcing tension members for the lower-portion of the concrete construction between the posts and the reinforcing tension members for the concrete construction that is immediately over the posts. In this way a reinforcing continuous girder effect is provided and this is enabled to be realized in an eflicacious manner due to the overlapping of the ends of the upper-peripherals with the corresponding ends of the lower peripherals; Each set H of upper intermediates comprises rods 24:, 25,26, 27 and'28. Said upper intermediates extend transversely of the sets of lower peripherals. The ends of said upper intermediates extend parallel with and overlap the corresponding ends of the sets of lower intermediates E. When the floor is deflected downwardly in the center there is a tensional strain in the lower portion of the flat flooring construction that is taken care of hy'the lower intermediates E. 'A corresponding tensional strain: is

created in the upper portion of theconcrete construction at the sides SD or ends ED of the panels, as the case may be, which is taken care of by the upper intermediates H. The coiiperating upper and lower inter- V mediates E and H provide the reinforcing tension members in what may be considered as'a continuous girder strip extending in the central part between rows of adjacent posts or columns. I

Each set K of the upper diagonals comprises rods 29, 30, 31, 32, 33 and 34. Said diagonals are located in the upper portion of the concrete floor construction over the posts or columns The ends of said upper diagonals K extend parallel with and overlap the corresponding ends of'the sets of lower diagonals F. :When the floor is deflected downwardly in the center there is a tensional str'ain in the lower portion of the floor construction that is in part taken care of by the lower diagonals]? and a corresponding tensional strain is created in a diagonal direction which is taken care of by the upper diagonals K over the posts. The upperand lower diagonals provide reinforcing tension members in" what may be consideredas a continuous girder strip eX- tending over diagonally arranged rows of posts or columns.

In the wall or outer panel illustrated in Figs. 6 and 7 there are employed lower peripherals, lower'intermediates, lower diagonals, upper peripherals, upper intermediates and upper diagonals in substantially vthe same arrangement as has been described in connection with the inner panel, with the exception, however, some of the peripherals at the wall end of the panel have been omitted, the upper diagonals have been omitted, the omission of such reinforcing members being availed of in order to facilitate construction and being rendered possible because of the flat panel construction merging into the wall of a building and because of additional reinforcements in the upper portion of the floor construction adjacent to the wall, as will hereinafter appear.

I Fig. 6 an end wall of the building is designated by VV-lV. It has the wall posts or columns WA provided with brackets CAin effect heads or caps on the wall columns. The inner columns are designated as A and are the same as the columns correspondingly designated and which have been previously described. The three sets of lower peripherals designated D, the two sets of lower intermediates designated E, four sets of upper peripherals G, three sets of upper intermediates H, two sets of lower diagonals F and four sets of upper diagonals K are the same in their position and function as the corresponding named and lettered sets heretofore described in connection with Figs. 1 to 5 inclusive. In Fig. 6

there are not shown any upper diagonals over the wall columns. There are shown lower peripherals constituting the set designated as D and comprising tension rods 35, 36 and 37 There are provided at or adjacent to each wall column WA a set G of upper peripherals which extend parallel to the wall. These upper peripherals are made longer than the peripherals Gr parallel there to and which are located at or adjacent to posts A. Each set G comprises rods 38, 39, 40, 41 and 42. There is also provided at or adjacent to each wall column WVA a set G of upper peripherals which'extend at right angles to the wall. Aset H of upper intermediates is provided at the wallportion of the panel. The upper, intermediates extend at right angles to the wall. These'upper peripherals G and also the upper intermediates H are made so as to extend into the wall or lintel of the buildingbut so as to terminate short of the exterior surface there v of. Each set G comprises rods 43, 44, 45, 46, 47 48, 49, 50, 51 and 52 and the set II comprises rods 53, 54, 55, 56 and 57. Because of the reinforcing strength of the peripherals at the wall of the building it isunnecessary to employ'the upper diagonalsover the wall columns but of course such upper diagonals could be employed if, for any reason, a designer desired todo so.

An important feature of the present invention resides in employing the'intermediates in association with the peripherals and 'diagonals whereby all parts of the panel, be it a wall panel or an inner panel, are properly reinforced against tensional stralns.

The several reinforcing members or bars heretofore described may be of steel and may be steel rods, either twisted or notched, or any other suitable material.

The improvements herein set forth are not limited to the precise construction and arrangement shown and described for they may be embodied in various forms and modifications without departing from the spirit and scope of the invention.

A flat flooring concrete construction to rest upon columns, comprising lower peripheral reinforcing members extending from column to column, sets of lower intersecting diagonal reinforcing members spanning the space between the diagonally opposed columns and sets of intersecting intermediate reinforcing members spanning the space between directly opposed sets of lower peripheral reinforcing members, the intermediates and diagonals carrying substantially the same proportion of the load.
